PURPOSE A primary barrier to elucidating the association between sedentary behavior (SB) and health outcomes is the lack of valid monitors to assess SB in a free-living environment. The purpose of this study was to examine the validity of commercially available monitors to assess SB. METHODS Twenty overweight (mean ± SD: body mass index = 33.7 ± 5.7 kg·m(-2)) inactive, office workers age 46.5 ± 10.7 yr were directly observed for two 6-h periods while wearing an activPAL (AP) and an ActiGraph…

Validity of two wearable monitors to estimate breaks from sedentary time.

This study demonstrates the use of expressing breaks from sedentary time as a rate per sedentary hour, a metric specifically relevant to free-living behavior, and provides further evidence that the activPAL is a valid tool to measure components of sedentary behavior in free- living environments.

Validating Accelerometers for the Assessment of Body Position and Sedentary Behavior

In particular, thigh-worn devices, namely the Move and the ActivPAL, achieved up to excellent validity in measuring sitting/lying body positions and sedentary behavior and are recommended for future studies.

Variability of Objectively Measured Sedentary Behavior.

When assessed over a 7-d measurement period, SB appears to be very stable from day to day, although there may be some small differences in time spent in SB and breaks in SB between men and women, particularly on weekend days.

Use of Objective Measures to Estimate Sedentary Time in Youth.

Compared to measured SB time, the VA <25 counts/10-s and VM <75 counts/ 10-s provided the most precise estimates of SB during free-living activity, which is needed to improve the AP and AG posture estimates.

Validation of a Smartphone App for the Assessment of Sedentary and Active Behaviors

Despite its inaccuracy, the app may be useful as a self-monitoring tool in the context of a behavioral intervention and future research may help to clarify reasons for under- or over-reporting of behaviors.

Empirically derived cut-points for sedentary behaviour: are we sitting differently?

Compared to the 100 cpm and 150 cpm thresholds, the empirically derived cut-points were not significantly different in terms of area-under-the-curve, but had lower mean bias for working and non-working times.

Comparison of subjective and objective measures of office workers' sedentary time

Validation of a Modified Version of the German Sedentary Behavior Questionnaire

A modified version of the widely used Sedentary Behavior Questionnaire compared to waist-worn accelerometers as an objective measurement was validated, and a significant gender difference in weekly sedentary time was found.

Feasibility of Measuring Sedentary Time Using Data From a Thigh-Worn Accelerometer

Thigh-worn accelerometry was feasibly deployed and should be considered for larger-scale national surveys, and male sex, underweight, obesity, education, poor self-rated health, television-viewing time, and having a sedentary occupation were associated with higher device-measured sitting times.



The validation of a novel activity monitor in the measurement of posture and motion during everyday activities

The activPAL physical activity monitor is a valid and reliable measure of posture and motion during everyday physical activities and may facilitate interventions aimed at reducing inactivity.

Objective and subjective measures of sedentary behavior and physical activity.

The activPAL and BAR showed convergence on both summary and concurrent time interval levels in both sedentary behavior and walking, and the comparative discordance between activation and BAR with ActiGraph was likely a function of different approaches used to distinguish sedentarybehavior from walking.

The validity and reliability of a novel activity monitor as a measure of walking

The activPAL monitor is a valid and reliable measure of walking in healthy adults and its accuracy is not influenced by walking speed, suggesting it may be a useful device in sports medicine.

Accelerometer output and MET values of common physical activities.

This study provides valuable information about data collection, metabolic responses, and accelerometer output for common physical activities in a diverse participant sample, and linear regression models are inappropriate for accurately predicting METs from accelerometers output.

Joint associations of multiple leisure-time sedentary behaviours and physical activity with obesity in Australian adults

Those who spent more time in sedentary behaviours (but were sufficiently physically active) and those who were insufficiently active (but spent less time in Sedentary behaviour) had a similar risk of being overweight or obese.

Amount of time spent in sedentary behaviors in the United States, 2003-2004.

The authors evaluate participants from the 2003-2004 National Health and Nutrition Examination Survey aged >/=6 years who wore an activity monitor for up to 7 days to provide the first objective measure of the amount of time spent in sedentary behavior in the US population.

Comparing the performance of three generations of ActiGraph accelerometers.

The results of this study revealed an improvement of the intermonitor variability by theGT1M monitor, however, the reduced sensitivity in low-count ranges in the GT1M may not be well suited for monitoring sedentary or light-intensity movements.

Objectively Measured Sedentary Time, Physical Activity, and Metabolic Risk

Independent of time spent in moderate-to-vigorous–intensity activity, there were significant associations of sedentary time, light-intensity time, and mean activity intensity with waist circumference and clustered metabolic risk.

Revisiting "how many steps are enough?".

The purpose of this article is to reprise, update, and extend the current understanding of dose-response relationships in terms of pedometer-determined PA, to advance evidence-based steps/day standards in both adults and children from a measurement perspective.

Sitting time and mortality from all causes, cardiovascular disease, and cancer.

These data demonstrate a dose-response association between sitting time and mortality from all causes and CVD, independent of leisure time physical activity and physicians should discourage sitting for extended periods.
